An automotive circuit tester, the VDIAGTOOL V210 Automotive Open & Short Finder, locates open and short circuits quickly and non-invasively. Peace of mind for DIYers and technicians who need fast, reliable fault finding. Will those features earn a permanent spot in a garage or workshop?
⚡ At a Glance
- • Tracing Accuracy: Receiver LEDs and buzzer change with signal strength to help pinpoint open connections, broken wires and current leaks
- • Best for: DIY mechanics, electricians and technicians needing quick fault diagnosis on DC 6–42V circuits
- • Not ideal for: High-voltage or non-DC systems outside the 6–42V range and users who need hands-free operation
Transmitter and receiver work together to locate open and short circuit points. Adjustable sensitivity and audible signals aid step-by-step fault finding.
Pinpoint Open and Short Circuits – With transmitter and receiver LEDs plus audible buzzer
Transmitter injects a signal into the circuit while receiver detects changes in signal strength; LEDs show open or short conditions and the buzzer changes tone as signal varies.
Locate breaker points, broken wires and current leaks quickly without stripping insulation, using audible and visual cues to guide the search.
Non-invasive Wire Tracing – Thanks to low-voltage signal tracing and insulated probe contact
Signal tracing operates across DC 6–42V and can follow cables through harnesses and behind panels without requiring exposed conductors.
Trace hidden wiring and confirm continuity without damaging insulation, making checks in situ straightforward and safe.
Hunt Intermittent Faults – With adjustable sensitivity and a flexible 7-inch probe
Receiver includes a sensitivity knob to increase detection of weak or intermittent signals while a flexible probe reaches awkward connectors and terminals.
Expose intermittent issues by flexing wires and monitoring tone changes, allowing detection of faults that only appear under movement.
